UDaily: Historian reflects on how 1970 event empowered a generation

Adam Rome, an environmental historian at the University of Delaware, wrote the book on Earth Day.

His The Genius of Earth Day: How a 1970 Teach-In Unexpectedly Made the First Green Generation, published in 2013, tells the story of what he calls “the most famous little-known event in modern American history.”

Everyone has heard of Earth Day, celebrated annually since 1970 on April 22, but many people today are unfamiliar with its origins and impact.
